CSU Secured Wireless Network

Important information regarding changes in wireless network security (4csuuseonly)

On Tuesday February 7, 2012 a new SSL (Secure Sockets Layer) certificate must be installed to securely authenticate users to the CSU secured wireless network (4csuuseonly).  This change may force you to change the configuration of some of your wireless devices.  

Most users will simply see a dialog box asking the user to validate the server or certificate. In this case simply click “Connect”, “OK”, “Continue”, or “Accept” to proceed connecting to the wireless network. (The dialog box message varies by operating system.) This will be a one-time task and subsequent connections will be seamless.

It is possible for MS Windows users to setup their computers before the actual change takes place without affecting their ability to connect presently. Updated connection guides are available at:

In some instances, iPhones and iPads may not connect to the wireless network until the profile for “4csuuseonly” is removed and re-added.
